LEDs (or OLEDs) used for lighting have recently been spotlighted as light sources of high efficiency lighting because they have higher energy efficiency than fluorescent lamps, sodium lamps, mercury lamps, and incandescent lamps. However, the LED (or OLED) is weak to heat, and in order to secure the lifetime and efficiency of the LED (or OLED), it is necessary to dissipate heat generated from the LED (or OLED). Therefore, the heat dissipation function has been regarded as an important function among the attributes that LED (or OLED) lighting equipment should have. If the heat dissipation function is insufficient, there is a problem that the life of the LED (or OLED) lighting device is also shortened rapidly.

Various efforts are being made to improve the heat dissipation efficiency of LED (or OLED) lighting equipment in order to secure reliability, energy efficiency and product life of LED (or OLED) lighting equipment.

Conventional heat sinks used in LED (or OLED) lighting use high heat LED (or OLED) lighting products in order to increase the heat dissipation area.
